Document Type and Number:
WIPO Patent Application WO/2010/057003
Kind Code:
A3
Abstract:
Improved inserts for use in side pocket mandrels which include one or more annular sealing elements that are formed of an elastomeric material that swell in response to heat or fluid saturation. When the insert is emplaced within a side pocket mandrel, the swellable elastomer can then be swelled, using either heat or fluid saturation, to cause the sealing element(s) to expand and seal against the seal bore of the side pocket mandrel.
